Steel wire braided rubber hoseIt is mainly composed of a liquid resistant synthetic rubber inner layer, a middle layer, a steel wire braided layer, and an outer layer. The inner layer has the function of withstanding pressure on the conveying medium and protecting the steel wire from erosion. The outer rubber layer can protect the steel wire from damage. The steel wire layer is a skeleton material that plays a reinforcing role. One of the things to pay attention to during production is the molding temperature of the rubber layer. Only by mastering the molding temperature of the hose can high-quality high-pressure hoses be produced. Here, we will briefly introduce the molding temperature of the rubber layer.

1. After measuring the raw materials according to the formula requirements, the rubber hose and plasticizer are added to the high-speed mixer for mixing. The specific requirements are the same as the mixing method for PVC rubber hose raw materials. When the temperature of the material reaches 110-120 ° C, put it into a cold mixer, stir and break up the clumped material, and lower the temperature of the evenly mixed material to below 45 ° C.

2. For the inner extruded high-pressure steel wire braided rubber hose, the temperature of the feeding section of the extruder barrel is 90-120 ℃, the temperature of the plasticizing section is 130-150 ℃, and the temperature of the homogenization section is 160-170 ℃. The temperature of the molding mold is 170-180 ℃.

3. The outer layer of extruded laminated steel fiber rubber hose has a feeding section temperature of 110-130 ℃, a plasticizing section temperature of 140-160 ℃, and a homogenization section temperature of 160-170 ℃. The temperature of the molding mold is 170-180 ℃.

The steel wire braided rubber hose assembly is a commonly used auxiliary equipment in hydraulic systems, used to connect various hydraulic components in the hydraulic system. Mainly used for hydraulic power transmission with working temperatures ranging from -40 ° C to 100 ° C, or for conveying high-pressure media such as water, gas, oil, etc., to maintain liquid circulation and transfer liquid energy. According to the usage conditions, choose the correct model and specification of the hose, and do not use or substitute it incorrectly.
